CLINICAL-THERMOMETER ATTACHMENT.

Specification of Letters Patent.

Patented Jan. '7, 1908.

To all whom it may concern: l

Be it known that I, RALPH F. Soimmnna, g a citizen of the United States,residing in the borough of Bronx, in the city, county, and State of NewYork, have invented certain. new and useful Improvements in Clinical-Thermometer Attachments, of which the following is a specification.

My invention relates to attachments for clinical thermometers and hasfor its object to construct the usual casing for such thermometers insuch. a manner as to utilize said casing to subject the thermometer tothe action of centrifugal force and thus to return the mercury to thebulb after use, by means of said centrifugal force.

My invention will be fully described hereinafter and the features ofnovelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings in which Figure 1 isan elevation of my improved device with parts in section; Fig. 2 is asimilar view of another form of my invention, and Fig. 3 is a similarview of still another form of my invention.

Referring more particularly to the form ol my invention shown in Fig. 1,A is the usual about when not in use and which is screwthreaded at itsopen end as indicated at E to receive the cap E. The casing A isprovided near its openend with two diametrically opposite openings Bwhich are slightly larger than the diameter of the body of thethermometer C. A flange or other enlargement D prevents the thermometerfrom be ing forced entirely through the openings B. In using this formof my invention the thermometer after having been read is inserted intoand through said openings B, as shown in Fig. 1, and. the casing A isscrewed partly into the cap E. This cap E is then held in the left handand the casing A is rapidly irotated back and forth by the right hand ofthe person using it, thus causing the thermometer to be rapidly movedback and 'forth in the arc of a circle. During this operation the cap Eserves as a pivot or bearing to permit the said case to be easilyrotated as described. A few turns of the casing with the thermometer inposition thereon will cause the centrifugal force to return themercuryto the bulb, thus doing away with the danger of breaking thethermometer as is frequently this broadly.

done when the thermometer is shaken to return the mercury to the bulb.

in the form 01 my device, shown in F ig. 2, the openings B are locatednear the center of the casing A and the closed end of said casing isconical as indicated at A. in using this .form, the thermometer isplaced in the openvings in the same way as shown in Fig. 1 and theconical end A of the :asing is inserted into the open end of the cap Eas shown in Fig. 2. This cap is held .in the left hand and the casing Ais twirled back and forth by the right hand in the same way as describedwith regard to the construction shown in Fig. l. in this instance theopen end of the cap serves as a bearing for the conical end of thecasing. Otherwise this form of my invention may be the same as the onehereinbefore described.

Referring now to Fig. 3, the openings B for receiving the thermometerare located in the cap E near its closed end and the cap is furtherprovided with an annular milled portion E in using this form the casingA is grasped in the left hand and a linger of the right hand is passedback and forth over the milled portion E of the cap. This causes the capwith the thermometer in position in the openings B to be rotated backand forth in the same manner and for the same purposes as hereinbeforedescribed. In this form the cap is rotated and the screwthreaded end ofthe casing forms the bearing or pivot in much the same way as describedwith regard to Fig. 1.

If desired the form of my invention shown in Fig. 1 may be used withoutthe cap, that is after the thermometer has been placed in the openings Bthe casing may be simply rolled back and forth between the hands of theuser.

My invention is thus extremely simple in construction and effective inoperation. It is further cheap to n'lanufacturc and can be embodied inpresent constructions with very little expense.

1 am aware that to return the mercury to the bulb of clinicalthermometers by centrifugal force is old and do not desire to claim Iam, however, not aware that the ordinary casing having openings thereinto receive the thermometer has ever been used for this purpose.

I claim.

The combination of a case provided with openings, a thermometeradapted to be projected through said openings at substantially rightangles to the axis of the case, and an enlargement at one end of saidthermoman enlargement on said thermometer to preeter to preventthe'thermometer from being 10 vfint the ltlhermlometfr from being forcedall forced all the Way through said openings. t e Way t roug saiopenings.
